The "symrdf failover" command returns the error: "Cannot proceed in the current RDF Consistency state except if the force flag is used"

The "symrdf failover" command returns the error: "Cannot proceed in the current RDF Consistency state except if the force flag is used."

Customer had enabled consistency mode on devices in this group.

This can be checked by running the following command:

C:\>symrdf -sid xxxx query -rdfg 86

When the consistency mode is enabled, you would be required to either disable it, or use the -force flag.

The customer can use the -force flag to proceed with the command, or alternatively they can disable consistency on the relevant group:

symrdf -g <dgname> disable

In the Solutions Enabler Symmetrix SRDF Family CLI Product Guide, the following is noted: "If consistency is enabled on SRDF/A-capable devices within the group, then the -force option must be applied for the failover, split, and suspend commands."
